'5 Claims. 1 This invention relates to rakes and more particularly to an improved stripper for therotary raking reel.

An object of this invention is toprovide an improved stripper construction which is adapted to be secured to the supporting frame of the reel and which includes means whereby the strippers or'guards will be yieldable with respect to the frame.

Another object of this invention is to provide in a side delivery rake a plurality of strippers for the rotary tines and which are so constructed and arranged as to provide resiliency to the strippers while at the-same time the strippers per se may be made o'f-substantially rigid material.

A further object of this invention is to provide in a construction of this kind an improved stripper for the rotary rake or reel wherein the op posite ends of the stripper bars are yieldably supported so as to prevent-bending or breaking of the rotary tines in the. event any material becomes clogged between the strippers.

A further object of this inventionis to provide a stripper construction of this kind wherein the stripper bars may be made out of any suitable materials such as flat, rQundQOr-the like, which has aninherent degree of resiliency, the stripper bars or rods being spring tensioned with respect to thesupporting frame so that theserods may have movement relative tothe frame With the foregoing objects and others which may hereinafter appear, the invention consists of the novel construction, combination and rangement of parts as will be more specifically referred to and illustrated in the accompanying drawings, wherein are shown embodiments of the invention, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invcntion as claimed. In the drawings:

Figure l is a vertical section of a reel or-rake having mounted on the frame thereof a stripper construction embodying this invention.

Figure 2 is a fragmentary plan view of rake structure. v

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 2. v

Figure 4 is a vertical section, partly in elevation, of a modified for-mof stripper construction.

Figure 5 is a fragmentary sectional View, partly in elevation, of another modification of this invention, and 1 Y I Figure 6 is a fragmentary vertical section of a further modification of this invention.

Referring to the drawing, the numeral Hidesignates generally a rotary rake or reelwhich mounted on a drive shaft H -mounted.for rotation with respect to a supporting frame generally the designated as [2. The supporting frame l2 includes a pair of longitudinal angle members 13 and M which have secured to the opposite ends thereof a. bowed guard member l5. The guard member I5 is adapted when the rake is in operative position to slidingly engage on the ground so that the tines it of the rake may contact with the material which is being picked up from the surface of the ground.

A plurality oi'strippers generally designated as I! are carried by the frame 12, and each stripper ll comprises a bowed or longitudinally bent bar having an arcuate lower portion [8 which is up wardly bent as at It and formed into a vertical extension 20. The extension 213 slidingly engages through an opening 2| which is formed in the horizontal side 22 of the angle member M, and a lower spring 23 bears at its upper ends against the lower face of the horizontal side 22 and at its lower end bears against a washer or collar 2.4 which may be fixed by means of a pin or weld 2 5 with respect to the vertical extension 20.

A second and upper springtt is disposed about the vertical extension 20, bearing at its lower end against the upper face of the horizontal side 22 and at its upper end a tensioning nut2'l .is threaded on extension 2!] with a washer 28 interposed between nut 2'! and spring 25. The opposite or forward portion of the bar I! includes an elongated vertical extension 29 which substantially longer than the vertical extension 20 and slidingly engages through the horizontal side 30 of the angle member 53. A lower spring 31 is disposed about the extension 29 bearing against the lower face of the horizontal side it! and also against a collar or washer 32 which is fixed by means of a pin or weld 33 against downward movement with respect to the rod orextension 29. An upper spring 34 is positioned about the upper end portion of the extension 29, bearing at its lower end against the upper face of the horizontal side 38. A spring tensioning nut 35 is threaded on the upper end of extension 29 and a washer 36 is interposed between nut 35 and spring 34. The provision of the upper and lower springs at the opposite ends of the stripper bar I! provides a means for yieldably resisting upward and downward movement of the stripper bar with respect to the frame members 13 and Referring now to Figure 4, there is disclosed a modified form of stripper bar,.g'enerally designated as 31. The bar 3] includes a lower 'arcuate portion 38 which terminates at its rear end in a bend 39, and the bend 39 is formed with a vertical extension 40. The extension 4!! is slida-ble through an opening provided in the horizontal side of the angle member M and a lower spring 4 l. engages beneath the angle member I4, being positioned about the extension 4.0 andbearingat its lower end against a washer or collar 42. A nut 43 is threaded onto the upper end of the extension 45 and provides a means whereby the spring 4| may be tensioned to thedesired degree. V r The opposite or forward end of the arcuate lower portion 38 is formed with an elongated vertical extension or supporting member 4'4 which slid"; ingly engages through the forward angle frame member l3. A spring 45 is positioned about the extension or supporting member 44 bearing at its upper end against the angle member l3 and at its lower end against a collar or washer 45 which is fixed by means of a .pin or weld 41 against downward movement with respect to the supporting member or extension 44. A nut 48 is threaded.

onto the upper end of the extension 44 bearing against the upper face of the angle member l3 and provides a means whereby the spring 45 may be tensioned to the desired degree.

' Referring now to Figure 5, there is disclosed another modification of this invention including a stripper bar 49 which has a configuration similar to the stripper bars I? and 3'1. In this form of the invention, the rear end of the stripper member 4'9 is formed with an upright extension 5!! slidingly engaging through the rear frame memher It, and the terminal upper end of extension 50 is formed with a horizontal sleeve 5|. A horizontally disposed resilient supporting bar or rod- 52 is fixed in any suitable manner with respect to the frame of the rake, and the rod or supporting member 52 loosely engages through the sleeve 5!. The sleeve 5| is held against endwise movement with respect to the supporting member 52 by means of oppositely disposed springs '53 and 54. One end of the spring 53 engages against the adjacent end of the sleeve 5| and the opposite end of the spring 53 engages against a was-her 55 which is fixed in any suitable manner with respect to the supporting member 52. The spring 54 bears at one end against the adjacent end of the sleeve 5| and the opposite end of the spring 54 bears against a washer 56 which may be held against movement away from the sleeve 54 by means of a pin or other fastening member 51.

The forward end of the stripper bar 49 is formed with an upright extension 58 which slidingly engages through the forward frame bar 13 and the terminal upper end of the extension 53 has securedthereto a sleeve 59. A forward supporting bar or rod 60 loosely engages through the sleeve 59, being secured in any suitable manner at the opposite ends thereof to the frame of the rake. Oppositely disposed springs BI and 62 engage against the opposite ends of the sleeve 59. and

j against washers 63 and 64, respectively, which are pinned or otherwise fixed relative to the supporting member '60.

Referring now to Figure 6, there is disclosed a further modification of this invention, there being 1 shown only one end of a stripper bar 65 which may be similar in configuration to the stripper bars I! and 31. The strip-per bar 65 is adapted to slidingly engage through the horizontal frame members of the rake structure, one of these frame The V 4 opposite ends of the stripper bars l? are yieldably held against upward and downward movement by means of the springs 23, 26, Si and 34.

As the rake is moving over, the surface of the ground, in the event an obstruction: should be encountered between the guards l5 at the opposite ends of the reel, this obstruction will strike the lower arcuate portion iii of one or more of the strip er bars IT. The stripper bars ll may which contacted the obstruction to their normal position which is a balanced positionformed by the oppositely disposed upper and lower springs.

The operation of the structure shown in Figure 4 is similar to that of the construction shown in Figures 1, 2, and. 3, with the exception that the springs 4| and 45 are tensioned by the threaded nuts 43 and 48. In this manner, the springs 4| and 45 may be placed under any desired. tension so that the stripper bars 31 may have upward movement resisted by the predetermined tension of the springs 4| and 45.

With the construction shown inFigure 5, the elongated supporting members 53 and form the yieldable support for the stripper bars so that these bars may have limited upward movement when an obstruction is encountered, and forward or rearward movement of the stripper bars on the supporting members 52 and 60 is resisted in either direction by the oppositely disposed springs 53 and 54 and springs 6| and 62.
